There are three methods to store tea: first, the refrigeration method, where the tea is sealed in aluminum bags and placed in a metal can, which is then stored in the refrigerator at 0 to 5 degrees Celsius; second, the vacuum-sealing method, where the tea is packed in bags from which air is removed and then sealed and stored normally; third, storage at room temperature, where the tea is divided into smaller packages and placed in cardboard boxes, which are kept in a cool, ventilated area at room temperature.

The main principles for storing tea are as follows:

1. Keep dry

High humidity can lead to mold and pests, so it's essential to keep tea dry. Store tea in a dry and well-ventilated place away from direct sunlight and high humidity. If the tea isn't sufficiently dry, let it air out to evaporate any excess moisture.

2. Prevent oxidation

Polyphenols in tea can easily oxidize when exposed to oxygen, which alters its aroma and flavor. To minimize contact with air, store tea in airtight containers such as sealed bags or tea cans. If you open the tea, quickly transfer it back into an airtight container.

3. Avoid odors

Tea readily absorbs odors, which can affect its aroma and taste. Store tea separately from other fragrant items. For long-term storage, you can place some dried spices like tangerine Peel or Cinnamon near the tea to help retain its aroma.

Conventional methods for storing tea:

Method one: The best containers for storing tea are tin cans, jars, and colored glass bottles. Next best are iron cans, wooden boxes, and bamboo boxes (bamboo boxes are not suitable for use in dry northern climates). Plastic bags and paper boxes are the least desirable. Many tea shops choose clay jars made of purple clay, wrap the tea in plastic film, seal the lid, and this method preserves the tea well.

Method two: Stainless steel tea cans and iron cans are also good containers for storing tea. You can directly pour the tea into the container and close the lid, creating a sealed environment that prevents air from entering and helps preserve the nutritional content of the tea. This method is very convenient.

Method three: For home storage, a small amount of tea can be stored in the refrigerator to keep it dry and Odor-free (alternatively, you can have the tea shop vacuum-seal your purchase, which you can then store in the fridge without opening for up to a year while retaining its original flavor. Note: once opened, be sure to protect against odors). You can also wrap the tea in moisture-proof film. In more developed areas, there are special refrigerators designed for tea storage, which work even better. Note: Oolong tea, Black Tea, and jasmine tea do not need to be stored in the refrigerator. Oolong and black teas contain lower levels of polyphenols and age more slowly, making them easier to store; jasmine tea has a strong floral fragrance that can be suppressed by low temperatures, reducing its freshness and intensity. Pu'er tea should ideally be stored at room temperature in a well-ventilated, dry place.

Method four: Another simple method is to buy large glass tea jars from the supermarket. These jars typically come with rubber seals around the edges, providing an excellent airtight seal that is both convenient and practical.

Method five: An older method for storing tea involves using foam boxes filled with quicklime. The quicklime is usually in block form and unslaked. The tea is tightly packed in small bundles, and the box is sealed, which keeps the tea fresh and prevents it from absorbing flavors.
